Define absolute dating techniques

Very often historical evidence is found in layers and older layers are further down that the top layers.

For example: If an archaeologist is studying past civilizations, the archaeologist may be able to say that in a particular location the ruins of one civilization were found to have been built on another and so the layers unearthed in an excavation convey the sequence of historical occupations without revealing the actual dates.

Absolute dating is the process of determining an approximate computed age in archaeology and geology.

Relative dating is determined by comparing its placement with that of fossils in other layers of rock.

Relative dating was a precursor to absolute dating.

Before absolute dating techniques were discovered, the age of a rock was a guesstimate at best.

Short Answer: The term relative dating is distinguished from absolute dating to make it clear that one does not get a specific estimate of the age of an object from relative dating, but one does get such an estimate of true age from absolute dating.

There are several techniques employed in both sets of methods. Long Answer: Sciences such as geology, paleontology and archeology are very interested in identifying the age of objects found and these scientists sometimes use both relative dating or absolute dating to characterize the age of the objects they study.

Similarly, relative dating is done by paleontologists who find layers of fossils.

By deducing which fossils are formed in the sequence of time, the periods when the particular fossilized entities existed can be arranged in order without the actual dates of when the fossils were laid down.
